[0001] The utility model relates to the technical field of street lamp foundation pile casting moulds, in particular to a street lamp foundation pile casting mould for municipal road construction. Background Art

[0002] With the rapid development of social economy, in the metallurgical industry, casting molds are molds used for casting cast iron in the ironmaking process. They are widely used in cast iron equipment of ironmaking enterprises. The foundation piles of street lamps used for construction on general roads are mostly cylindrical. The mold cavity in the casting mold needs to be set to a cylindrical shape so that the liquid metal can enter the mold cavity and solidify into shape.

[0003] However, the overall structure of the existing casting molds is mostly set to a cylindrical tube shape, and the diameters at the upper and lower ends are the same, which makes the overall structure lighter in weight. The center of gravity of the overall structure is located at the upper end, making the overall casting mold A and casting mold B less stable, causing the overall structure to be easily overturned. Therefore, it does not meet the existing needs. In this regard, we propose a street lamp foundation pile casting mold for municipal road construction. Utility Model Content

[0004] The purpose of the utility model is to provide a casting mold for street lamp foundation piles for municipal road construction, so as to solve the problem that the overall structure of the casting mold proposed in the above background technology is mostly set to a cylindrical tube shape, and the diameters of the upper and lower ends are the same, which leads to the overall structural gravity being lighter, and the center of gravity of the overall structure is located at the upper end, so that the overall casting mold A and the casting mold B have poor stability performance, resulting in the problem that the overall structure may be easily overturned.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a casting mold for street lamp foundation piles for municipal road construction, comprising a casting mold A, one side of the casting mold A is snap-connected with a casting mold B, a casting cavity is provided inside the casting mold A and the casting mold B, three semi-annular grooves are provided on the surfaces of the casting mold A and the casting mold B, the front and rear ends of the semi-annular grooves on the surface of the casting mold A are fixedly connected with matching blocks, an insertion groove is provided in the matching block, the front and rear ends of the semi-annular grooves on the surface of the casting mold B are fixedly connected with connecting blocks, one side of the connecting block is fixedly connected with a plug-in block, and the plug-in block is inserted in the plug-in groove inside the matching block.

[0006] Preferably, the cross-sectional surfaces of the casting mold A and the casting mold B are configured as a frustum structure that is narrow at the top and wide at the bottom.

[0007] Preferably, the upper end of the matching block is fixedly connected to an outer cylinder, an inner cavity is provided inside the outer cylinder, the upper end of the inner cavity is connected to a spring, and the lower end of the spring is connected to a movable plate.

[0008] Preferably, a pulling column is fixedly connected to the middle of the movable plate, and the pulling column passes through the middle of the outer cylinder.

[0009] Preferably, an inserting circular groove is provided at the upper end of one side of the inserting block, and the lower end of the pulling column is inserted into the inserting circular groove.

[0010] Preferably, a pulling hole is provided through the front and rear of the upper end of the pulling column.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. The utility model sets the cross-section of the casting mold A and the casting mold B to a frustum structure that is narrow at the top and wide at the bottom. This setting makes the bottom of the casting mold A and the casting mold B stable. When the liquid metal flows into the casting cavity, the bottom of the casting mold A and the casting mold B is squeezed by the gravity of the liquid metal. The bottom of the casting mold A and the casting mold B is wider, so that the overall structure is more stable under the squeeze of gravity.

[0013] 2. The narrower structure of the upper ends of the casting molds A and B in the present invention not only reduces the loss of manufacturing materials, but also makes the overall upper end lighter, so that the center of gravity of the overall structure moves downward, thereby improving the overall stability of the casting molds A and B.

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] See also Figures 1 to 4 The utility model provides an embodiment: a street lamp foundation pile casting mold for municipal road construction, including a casting mold A2, a casting mold B3 is connected to one side of the casting mold A2, a casting cavity 1 is provided inside the casting mold A2 and the casting mold B3, three semi-annular grooves 4 are provided on the surfaces of the casting mold A2 and the casting mold B3, and matching blocks 5 are fixedly connected to the front and rear ends of the semi-annular grooves 4 on the surface of the casting mold A2, and the setting of the semi-annular grooves 4 enables the matching blocks 5 and the connecting blocks 6 and other components inside thereof to be fixedly connected;

[0021] An insertion groove 10 is provided in the matching block 5, and the front and rear ends of the semi-annular groove 4 on the surface of the casting mold B3 are fixedly connected with connecting blocks 6, and one side of the connecting block 6 is fixedly connected with a plug-in block 7. The plug-in block 7 is inserted into the insertion groove 10 inside the matching block 5. The arrangement of the matching block 5 and the plug-in block 7 enables a fixed connection between the two casting molds B3. This connection method enables a snap-on connection between the casting mold A2 and the casting mold B3, thereby enabling a casting cavity 1 to be formed between the casting mold A2 and the casting mold B3. When in use, liquid metal is cast inside the casting cavity 1.

[0022] The cross-sectional surface of the above-mentioned casting mold A2 and the casting mold B3 is set to a conical structure that is narrow at the top and wide at the bottom. This setting makes the bottom of the casting mold A2 and the casting mold B3 stable. When the liquid metal flows into the casting cavity 1, the bottom of the casting mold A2 and the casting mold B3 is squeezed by the gravity of the liquid metal. The wider bottom of the casting mold A2 and the casting mold B3 makes the overall structure more stable under the squeeze of gravity. The narrower structure of the upper end of the casting mold A2 and the casting mold B3 not only reduces the loss of manufacturing materials, but also makes the overall upper end lighter, so that the center of gravity of the overall structure moves downward, thereby improving the overall stability of the casting mold A2 and the casting mold B3.

[0023] The upper end of the matching block 5 is fixedly connected to the outer cylinder 8, and the inner cavity 13 is provided inside the outer cylinder 8. The upper end of the inner cavity 13 is connected to the spring 12, and the lower end of the spring 12 is connected to the movable plate 14. The middle of the movable plate 14 is fixedly connected to the pulling column 9, and the pulling column 9 runs through the middle of the outer cylinder 8. The spring 12 has a stretching elastic force, and the spring 12 has a downward extrusion performance on the movable plate 14;

[0024] The upper end of one side of the plug-in block 7 is provided with a plug-in circular groove 11, the lower end of the pulling column 9 is inserted into the plug-in circular groove 11, and the upper end of the pulling column 9 is penetrated by a pulling hole at the front and rear;

[0025] The plug-in block 7 is inserted into the insertion groove 10 inside the matching block 5, wherein the stretching elastic force of the spring 12 presses the movable plate 14 and the pulling column 9 downward, so that the pulling column 9 moves downward and is inserted into the plug-in circular groove 11 at the upper end of the plug-in block 7, so that the entire plug-in block 7 and the matching block 5 can be plugged and connected, and then the casting mold A2 and the casting mold B3 can be closely fitted, so that a casting cavity 1 is formed between the casting mold A2 and the casting mold B3, and liquid metal is cast in the casting cavity 1;

[0026] When the liquid metal inside the casting cavity 1 cools down, the user pulls the integral pulling column 9 upward, so that the integral pulling column 9 drives the movable plate 14 to move upward, and the movable plate 14 squeezes the spring 12 inside the outer cylinder 8. The elastic force of the spring 12 itself is squeezed and deformed, so that the lower end of the pulling column 9 is continuously disengaged from the plug-in circular groove 11 at the upper end of the plug-in block 7. This operation also enables the plug-in block 7 to be disengaged from the inside of the plug-in groove 10, thereby realizing the separation between the matching block 5 and the connecting block 6. Finally, the casting mold A2 and the casting mold B3 are separated, so that the casting cavity 1 inside the casting mold A2 and the casting mold B3 shapes the liquid metal.

[0027] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.
